- York, have invented certain new and useful Improvements in Tanks, lowing is a specification.

This invention relates to tanks or vessels for containin -highly explosive fluids such as gasolene, nap tha or the like; and has for its object to provide an imoroved safety device whereby upon abnormal heat of a dangerous character generated in the vicinity of the vessel, the vapors generated in the tank, or the liquid itseli, to a certain extent are permitted to esca e, yet flame will not be permitted to reach t e liquid or vapor in the tank itself by back firing.

A further object of the invention is to provide an im roved means for drawing on the contents or the tank without permitting ignited vapor to return into the tank.

In the accompanying drawing illustrating embodiments of the resent invention, Figure 1 is a vertical longitudinal section through the apparatus, certain parts being shown in elevation. Fig. 2 is a similar view of a modification. Fi 3 shows the spring safety valve in vertica section. Fig. 4 is a section on the line, 4 4 indicated in Fig. 3. Fig. 5 shows in section the escape opening with the apertured members. Fig. 6 is a section through the outlet valve member; and Fig. 7 shows a spring valve at the end of the outlet tube.

The tank or vessel T in the present instance is shown asof cylindrical shape such as the'tank used on motor vehicles or boats for carrying a supply of asolene or naphtha forthe engine. A suitab e outlet pipe is provided communicating with the upper ortion of the tank, and a valve is arranger in the outletpipe that is normally retained closed by a member that is either inflammable or otherwise weakened or disrupted by heat. Means are provided for o erating this valve upon release of 'the sai retaining means w iereby the outlet will be automatically of which the fol opened as soon as there is suflicient heat to operate the said means. Thereupon the vapor 1n the tank can escape as fastas generated and even the liquid contents may flow out.

In the construction shown in Fig. 1 an outlet pipe 12 extends into the tank at the bottom and upward and connects with a socket member 13. ternally at its upper part and is engaged by a hollow lug 14 screwing in an internally threade sleeve 15 that is inserted in a bore This member is threaded exin the top'of the tank. Suitable registering I bores 16 in the members 14 and 15 gives access from the tank into the interior of the sleeve 13. One or more a ertured plates or disks are placed in the s eeve 13, such as wire gauze disks '17 and 18 which will prevent any flame that might pass back through the tube 12 from igniting the vapor in the tank. In a horizontal extension 19 of the outlet 12 is a shut-off cock having a plug 20 with a single transverse bore 21 rotatable I in the cock frame 22. A spring 23 betweenthe frame and the plug tends to shift the plug to brin its bore 21 in alinement with the outlet pipe and open the passa e, the movement of the plug being limited y pin 26 engaging abutments 27 and 28 in the frame. A coil spring may be used as shown. To retain the plu normally closed, its handle 29 is connected with a suitable controlled device, such as a textile cord 30.

ortion of' the tank by a suitable infiammab e or heat Upon a large amount of heat occurrin in the vicinity of the tank, this string wil i,

and burn off, thereby releasing the handle 29. The coil spring 23 will therefore at once turn the plug to the open osition, giving an outlet to the tank throng 1 the pipes 12 and 19. In the case of a motor car, the outlet pipe may connect with the muffler M by a P pe In the construction illustrated in Fig. 2, the outlet pipe 33 connects with the top of the tank instead of passing up through the tank from the'bottom. But the construction and operation of the device is substantially the same. The cook 34 hasits handle 35 held in the open position by cord 36 of inflammable material. A hi h degree of heat will ignite this cord releasing the handle of the cock, Whose construction being the same as shown in Fig. 3 will at once open and per- I frame 41 is made rotatable on the pluglso that the passage 42 in the frame can be brought to register with the transverse part of the passage 43 in the plug, as indicated in- Fig. 6. An outlet pipe 44 leads from the frame 41 of the cock, and at its lower end is a valve member 45 in which. operates a spring valve 46 normally closing the oplefning in the valve seat wall 47 therein. 1 desired, a wire gauze disk 48 ma be placed the bottomportion of this out et, to prevent shifted ninety degrees, and the valvewould F be held in operative position, that is would be held open by the inflammable cordyupon rupture of the cord by heat, the spring would shift the valve to 1ts safety position in which the flow of the gasolene from the tankto any suitable member, such as a carbureter, would be arrested.

Having thus described my invention, 1

claim:

1. Asafety device for tanks comprising an outlet member leading from the top portion of the tank, a cock in said outlet memberhaving a rotary plug with a transverse bore, a coil spring between said plug and the cook frame tending to movethe plug to the open the tank retaining the plug in the closed position, whereby rupture of the cord from ignition thereof will permit the spring to swing the plug to open position.

v2. A safety device-for tanks comprising an outlet member leading from the tank, a cock in the outlet member having a rotary plug, a coil sprin' connected between the plug and the cock ame tending'to move the lug to safety position, and an infiammab e cord connected with the plug to retain it in operative position, whereby ru ture of the cord from ignition will permit tile spring to swing the plug to open position.
